Vegas was 2, March 28th, he was neutered at 4 months old (we adopted him at 4.5 months old) he has ALWAYS humped! My son's dog a female spayed Pit/Lab mix is his favorite. Yesterday my son brought his Pitt over along with his new male neutered Boston Terrior, Vegas checked out the new Boston sniffed a few minutes and went straight to Krillen and tried to hump her. This goes on every time she is here!!
it is so obnoxious!!!!!
EVERYTIME he does this I put him down, hold/pin him until he is calm and let him up, and I swear within 10 min. he is trying it again. He wares me out and makes the visit unpleasant every time. He can't even reach her so he is basically holding on to her side AIR HUMPING. I know it is a dominence thing, but it has been almost 2 years of this bad behavior of his. Is there any thing else I can do to him? I have put him in his crate for time outs and he just sits in there and barks obnoxiously until I let him back out to see Krillen (Oh it can be my company humans, as well as Krillen) I am so over it and I was so mad yesterday that I took a rolled up magazine and whacked his A*S!!
ANY other suggestions would be more than appreciated!!
